[0002] With the acceleration of urbanization and the rapid development of energy storage technology, the fire safety issues of energy storage equipment have become increasingly prominent. The reliability and stability of the fire protection system are directly related to the safety of people's lives and property. A large number of fire protection sensors are used in the fire protection system, such as smoke detectors, temperature sensors, etc. These sensors can issue alarms in time at the early stage of a fire, which plays an important role in reducing losses.

[0003] However, during the installation or maintenance of fire sensors, they need to be coded. Traditional fire protection systems use a fire host connected to the fire sensor to collect data and process the code. Since the fire host integrates functions such as data collection, coding and control, it is not only expensive, but also bulky, inconvenient to disassemble and carry, and greatly occupies the space of the energy storage device. In addition, it is not suitable for other application scenarios in small spaces. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following are specific embodiments of the present utility model in conjunction with the drawings, further describing the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the attached drawings). If this specific posture changes, the directional indications will also change accordingly.

[0024] As Figures 1 to 4 shown, a portable coding device for a fire sensor includes a housing 100, a communication analyzer 200, a switching power supply 300, a first wiring terminal 400, a second wiring terminal 500, a third wiring terminal 600, a PC interface 700, an indicator light 800, and a heat dissipation hole 900.

[0025] As Figures 1 to 4 shown, a portable coding device for a fire sensor includes:

[0026] A housing 100 having an accommodation cavity, and the housing 100 is provided with a first wiring terminal 400 and a PC interface 700;

[0027] A communication analyzer 200 and a switching power supply 300 are arranged in the accommodation cavity;

[0028] The communication analyzer 200, the fire sensor (not shown in the figure), and the switching power supply 300 can all be connected to the first wiring terminal 400, so that the switching power supply 300 supplies power to the communication analyzer 200 and the fire sensor, and the computer terminal can be connected to the PC interface 700 and form a communication connection with the communication analyzer 200 through the PC interface 700. The design of the first wiring terminal 400 enables the switching power supply 300 to supply power to the communication analyzer 300 and the fire sensor, and enables the communication analyzer 300 to form a communication connection with the fire sensor. The setting of the PC interface 700 enables the computer terminal to form a communication connection with the communication analyzer 300, so that the computer terminal can encode the fire sensor through the communication analyzer 200. This design enables the function of encoding the fire sensor to be separated from the fire host, and users can use it according to actual needs (when the energy storage device is equipped with a BMS system for controlling and monitoring the fire sensor, the fire sensor only needs to be encoded during the initial installation or commissioning stage). This undoubtedly breaks the traditional rule of requiring the fire host to perform encoding, enabling users to not need to configure a costly fire host, effectively saving the cost of the fire protection system and reducing the occupancy of the space of the energy storage device. In addition, through the settings of the first wiring terminal 400 and the PC interface 700, the computer terminal can encode the fire sensor intelligently and efficiently, and at the same time enables the coding device to be reused, effectively improving the utilization rate of the coding device.

[0029] Specifically, as Figures 1 to 4As shown in the figure, in this embodiment, the housing 100 is made of metal and includes a bottom plate 110 and a housing cover 120 that are separately arranged. After the bottom plate 110 and the housing cover 120 are enclosed, a rectangular accommodation cavity for placing the communication analyzer 200 and the switching power supply 300 is formed, and the bottom plate 110 and the housing cover 120 are detachably connected. The design of the housing 100 not only provides protection for the communication analyzer 200 and the switching power supply 300, but also improves the convenience of disassembly, assembly and maintenance of the communication analyzer 200 and the switching power supply 300 through the split design.

[0030] In this embodiment, the bottom plate 110 includes a horizontally arranged bottom surface 111. The communication analyzer 200 and the switching power supply 300 are arranged on the bottom surface 111 in a staggered manner and form a detachable connection or a fixed connection with the bottom surface 111. On the one hand, it ensures the support for the communication analyzer 200 and the switching power supply 300.

[0031] In this embodiment, when the communication analyzer 200 and the switching power supply 300 are detachably connected to the bottom surface 111, the bottom surface 111 is connected to the communication analyzer 200 and the switching power supply 300 by bolts (not shown in the figure) or straps (not shown in the figure), and the bottom surface 111 is provided with first mounting holes 114 for the bolts or straps to pass through. When the communication analyzer 200 and the switching power supply 300 are fixedly connected to the bottom surface 111, the bottom surface 111 is welded or bonded to the communication analyzer 200 and the switching power supply 300. Preferably, in this embodiment, the communication analyzer 200 is detachably connected to the bottom surface 111 by a strap, and the switching power supply 300 is detachably connected to the bottom surface 111 by a bolt, which improves the convenience of disassembly, assembly and maintenance of the communication analyzer 200 and the switching power supply 300 while ensuring the connection reliability.

[0032] In this embodiment, the bottom plate 110 further includes a first connecting edge 112 and a second connecting edge 113 that are respectively perpendicular to both ends of the bottom surface 111. The first connecting edge 112 and the second connecting edge 113 are integrally formed with the bottom surface 111, and the bottom plate 110 is formed in a groove shape. Among them, a first wiring terminal 400 is vertically provided on the first connecting edge 112, and one end of the first wiring terminal 400 is inside the accommodation cavity and the other end is outside the accommodation cavity. A PC interface 700 is provided on the second connecting edge 113, and the positions of the first wiring terminal 400 and the PC interface 700 respectively correspond to the position of the communication analyzer 200. This design optimizes the layout of the first wiring terminal 400 and the PC interface 700, which not only enables the shortest-distance wiring when connecting the communication analyzer 200, the switching power supply 300, the fire sensor and the computer terminal, ensures the compactness of the overall structure of the coding device, but also improves the convenience of user operation.

[0033] In this embodiment, the first terminal 400 forms a detachable connection or a fixed connection with the first connecting edge 112. When the first terminal 400 and the first connecting edge 112 are detachably connected, the first terminal 400 and the first connecting edge 112 are connected by bolts (not shown in the figure), and the bottom plate 110 is provided with second mounting holes 115 for the bolts to pass through. When the first terminal 400 and the first connecting edge 112 are fixedly connected, the first terminal 400 and the first connecting edge 112 are welded or bonded. Preferably, in this embodiment, the first terminal 400 and the first connecting edge 112 form a detachable connection by bolts, and the first connecting edge 112 is provided with through holes for the first terminal 400 to pass through. This design improves the convenience of disassembly, assembly and maintenance of the first terminal 400 while ensuring the connection reliability.

[0035] In this embodiment, a second terminal 500 and a third terminal 600 are further vertically provided on the first connecting edge 112. The second terminal 500, the third terminal 600 and the first terminal 400 are arranged in a straight line. One end of the second terminal 500 and the third terminal 600 is located inside the accommodating cavity, and the other end is located outside the accommodating cavity. The switching power supply 300 and the AC power supply can be connected to the second terminal 500 to supply power from the AC power supply to the switching power supply 300. The switching power supply 300 and the DC power supply can be connected to the third terminal to supply power from the DC power supply to the switching power supply 300. Thus, the coding device can support AC and DC power inputs, expanding the adaptability of the coding device.

[0036] Preferably, in this embodiment, the positions of the second terminal 500 and the third terminal 600 correspond to the position of the switching power supply 300, so that the shortest distance wiring is realized between the switching power supply 300 and the second terminal 500 and the third terminal 600, further ensuring the compactness of the overall structure of the coding device.

[0037] In this embodiment, an indicator light 800 for forming a communication connection with the communication analyzer 200 is further provided on the second connecting edge 113. Among them, when the communication analyzer 200 is in the normal coding state, the indicator light 800 shows green; when the communication analyzer 200 is in an abnormal state, the indicator light 800 shows red. This design enables the working state of the communication analyzer 200 to be intuitively displayed, greatly facilitating the user to monitor the operation of the coding device, thereby ensuring the reliability of coding.

[0038] In this embodiment, the shell cover 120 is detachably connected to the bottom plate 110 by bolts.

And the bottom plate 110 is provided with extension edges 116 perpendicular to the relative positions of the third connecting edge 122 and the fourth connecting edge 123. The extension edges 116 are detachably connected to the third connecting edge 122 and the fourth connecting edge 123, effectively ensuring the stability and reliability of the connection between the shell cover 120 and the bottom plate 110.

[0039] In this embodiment, a plurality of heat dissipation holes 900 are provided on both the third connecting edge 122 and the fourth connecting edge 123. The heat dissipation holes 900 are in the shape of a waist-shaped hole, arranged in a line along the length direction of the third connecting edge 122 and the fourth connecting edge 123, and communicate with the accommodation cavity. This design is beneficial to the heat dissipation of the switching power supply 300 and the communication analyzer 200, effectively improving the service life of the coding device.

[0040] In this embodiment, the switching power supply 300 supports the input of 220V alternating current and 24V direct current, and can convert the alternating current and direct current into 24V direct current output.
